Features

• Make stuff break up on impact with other stuff!
• Make stuff break up when there's nothing underneath supporting it!
• Make stuff break up for no reason whatsoever!
• Make stuff explode!
• Make stuff make sounds when it breaks up!
• Make stuff make particles when it breaks up!
• Things can also be configured to only partially break apart, depending on impact velocity.
• Includes an example game where you can throw a ball at a cube. It's funner than it sounds.

How to use

• Make an unbroken and a broken version of your object. I recommend using Blender's cell fracture feature.
• Add 'Destruction/Assets/Scripts/Destruction.cs' to the unbroken version.
• Mess with the settings until you get the desired breaking effect.
• For examples, see 'Destruction/main.unity'.
• Use Destruction.Break() to break things via a script, or Destruction.BreakWithExplosiveForce(float, float) to break things with explosive force via a script.
